Brush-cutting mower with an orientation bloc driven by an orientation cylinder

摘要

The cutter has a frame (2) on which an orientation block (3) controlled by a swing cylinder (7) is articulated. The block supports arms (5, 6) carrying an operating head (8). A support (10) for the swing cylinder is pre-stressed to a position and is moved when one arm or the head collides with an obstacle during retreating of the cutter in order to allow forward retraction of the cylinder, arms and the head.
